Barney Frank Takes Over MSNBC's The Last Word, Blasts Warren Supporters

Last night MSNBC’s Lawrence O’Donnell all but officially made liberal former Congressman Barney Frank a co-host on his program “The Last Word With Lawrence O’Donnell”. The Massachusetts Democrat appeared on the first 3 segments, spanning 40 minutes. This included a scalding attack on fellow liberal Ben Wikler of MoveOn.org for daring to lead a movement encouraging Senator Elizabeth Warren to challenge Hillary Clinton for the Democratic nomination for president.
